DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

As will be further described with reference to the succeedingillustrations, the present invention discloses a system/assembly, kitand method of assembling a plurality of track supports with to asurrounding fascia associated with an air intake opening, such as in onenon-limiting application including a piece of outdoor located HVACequipment including an opening revealing condenser coils, these incombination with a variety of screens/coverings, fasteners forsupporting the screen on the assembled supports, and optional end-to-endand corner adaptors/plugs for arranging the track supports according toany desired orientation. As will be explained in further detail, thepresent invention enables attachment of any number of the support tracksto the face of air handling mechanical equipment, this including the useof magnets to accomplish releasable attachment of the elongated supportsto the surface of the air intake face. Other variants contemplate any ofadhesives, including two sided tape or glue, as well as conventionalfasteners (screws, bolts, etc.) for securing the track supports to theintake face.

Referring to FIG. 1, an exploded view is generally depicted of thechannel lock filter fastening system according to a first embodiment ofthe present invention and exhibiting a single pair of upper and lowerhorizontal extending and fascia supporting rails, see at 10 and 12,which are secured at extending locations along a fascia surface 2associated with an air intake structure 4 (such further understood toinclude any suitable type of air handling mechanical equipment notlimited to air conditioner condenser units, cooling towers etc.). Asfurther depicted in each of succeeding views FIGS. 3-6, each of therails (see for example first upper horizontal extending rail 10)exhibits a three dimensional, and typically modified “U”, shape with abase surface (see at 14 in each of FIGS. 3-6).

A plurality of spaced apart apertures are defined by inner perimeterextending circular edges 18 (see again rail 10 in each of FIGS. 1 and2). A plurality of screw fasteners 20 are provided and insert throughthe circular apertures in order to fasten the rails 10 and 12 inhorizontal and parallel extending fashion above and below an intakeopening or area which is further generally designated at 6 in each ofFIGS. 1-4.

A filter screen 22 is provided, typically exhibiting a flexible meshlike material and including a surrounding reinforced outer portion 24.First 26 and second 28 pluralities of grommets (such interpreted toinclude metal ringlets or the like which are molded, press fit orotherwise affixed), extend along top and bottom outer hem extendinglocations of the reinforced outer portion 24.

A plurality of bolt fasteners 30 are provided and are identical inconstruction as with the various edge extending grommets or screwfasteners. As best shown in FIGS. 3-6, an enlarged head 32 (typicallyhexagonal shaped) is dimensioned so that it establishes a minor degreeof clearance with the inner extending edges of the associated channeldefined in the selected rail 10. This facilitates the bolts 30 to besuccessively installed through an open accessible end of the rail 10(see FIG. 5) and traversable along the channel interior to desiredintermediate locations, and with an end 34 of each bolt shaft projectingbeyond a slot (see walls 36 and 38 in partially exploded view of FIG. 3)defined in a forward spaced projecting edge of the rail.

At this point, and viewing FIGS. 1, 4 and 6 collectively, the filterscreen 22 is applied such that the ringlets 26 are successively seatedover the projecting shaft ends 34, following which a plurality of nuts,by non-limiting example depicted as wing nuts 40, are applied over theexposed shaft ends and are rotated into a tightening arrangement inorder to secure the filter screen to the rails 10 and 12. Also depictedare a plurality of washers 42 (see FIG. 6) this also contemplating theadditional or alternate use of lock washers (further at 44 in FIG. 6)and so as to prevent the filter from becoming inadvertently loosenedfrom the intake structure fascia.

Alternative to separately provided washers/lock washers, it is alsoenvisioned that suitable washer/lock washer portions can be integrallyformed into the wing nut (or other nut) construction. It is furtherenvisioned that, referring to FIG. 3, a suitable nylon coating 46 can beapplied to the inner threads associated with each wing nut 40 and whichcan be accomplished both in combination or alternate the incorporationof any type of separately utilized or integrally formed lock washers. Itis further understood that the configuration and dimensioning of theenlarged bolt heads is such that, during twisting application of thenuts 40, the heads 32 do not turn or rotate within the channels (seeagain FIGS. 3 and 4), such otherwise impeding the ability to quicklyapply or remove the nuts 40.

FIG. 2 is a view similar to FIG. 1 of a system according to a secondembodiment which differs only to the extent that it adds a secondvertical pair of intake face mounted rails 48 and 50 applied to oppositeand vertically extending sides of the fascia 2 in such a fashion thatthe first (10 and 12) and second pairs (48 and 50) of rails collectivelyestablish a generally rectangular shape (this including a square shapein the instance in which the sides of the intake opening and the lengthsof all the rails are co-equal). Otherwise, the filter 22 is aspreviously disclosed in claim 1 with the corresponding modification toinclude additional grommets 26 likewise extending along the verticalside edges of the reinforced outer frame (also hem or skirt) withcorresponding additional bolts 30, wing nuts 40 and washers 42 likewisebeing provided so as to progressively secure the filter 22 along each offour interconnecting edges and as opposed to only two upper and loweredges as is the case in the illustration of FIG. 1. Such an assemblyoption as depicted in FIG. 2 contemplates, without limitation, that thebolts, nuts and washers associated with the upper rail 10 are firstassembled, following which the sides 48 and 50 are progressivelyassembled such as further by individually supporting the bolts withinthe vertical channels during progressive assembly of the nuts andwashers. That said, the present invention does not preclude or limit anyparticular assembly protocol or sequence beyond that which is possibleowing to the structural aspects of the design.

Referring now to FIG. 6A, a partially exploded perspective of amodification of the assembly of FIG. 6 and showing an arrangement oftwist caps 52 in use with the fasteners (threaded shafts 30 which arealso termed “snug nuts” as well as an equal number of hex heads 32) ofFIG. 5. The twist caps depict collars which are interiorly threaded froman open inner end (not shown) and further each include a triangular (orother suitable and polygonal) shaped gripping end 54. The caps 52 arefurther constructed of a plastic or other suitable material.

As additionally shown in FIG. 6B, an equal plurality of modified washers56 are provided, each of these including a protuberant collar 58defining an interiorly threaded profile 60. The bolts (hex head 32 andstem 30) are pre-installed into an open channel end defined in amodified support track (see at 62, 64 and 66 in FIG. 6 arranged aboutthe intake opening of the associated structure 4) and so that thethreaded stems 30 projecting through the front disposed slot in themanner depicted. The elongated track supports are similar in applicationto those previously disclosed at 10 and 12 in FIG. 1 and can include aslightly modified extrusion profile and, as will be further described,can be attached both to the face of intake structure and interconnectedin end-to-end fashion according to a variety of differentconfigurations.

A flexible ply material or covering, such as any screen or mesh utilizedin a filtration application or an opaque covering in the instance of asealing or winterizing application, is provided at 68. The material mayinclude a reinforced outer perimeter 70 and can further exhibit aplurality of reinforced ringlets 72 (also termed grommets) integratedinto the outer perimeter of the material. In application, and as againreferenced in the partial plan cutaway of FIG. 6B, a selected engagementis established between a bolt, twist cap and modified washer withthreaded interior collar against first and second surfaces of the filterscreen or other supported covering 68.

FIG. 6C is a view similar to FIG. 6A of a related variant in which amodification of the outer twist cap, see at 74 in comparison to as shownat 52 in FIG. 6A) integrates a threaded bolt 76. The bolt fasteners ofFIG. 6A are removed in this variant and substituted by a reconfiguredwasher 78 with threaded central support collar 80. The washers 78 eachexhibit linear upper 82 and bottom 84 edges and are dimensioned suchthat they are insertable through the open end of the track supports 62,64, 66, et seq.

In practice, and owing to the lack of a projecting component through thefront defined and slot accessible face of each track support, thethreaded portions 76 of the twist nuts 74 are typically pre-engagedthrough the material ringlets 72 and the inner threaded collars 80 ofthe modified/flattened washers in an intermediate assembled fashion,such prior to the washers being installed from the open channel ends ofthe supports. In this fashion, the twist nuts 74 are used fortranslating the washers within the supports prior to finishedtightening. This is further depicted in FIG. 6D which, similar to FIG.6B, is a partial plan cutaway of a selected engagement establishedbetween the modified screw cap and track insertable washer of FIG. 6Cagainst first and second surfaces of the filter screen or othersupported covering. As further shown, the linear edges 82/84 of themodified washers 78 can be dimensioned, if desired, such that theyestablish a desired friction engagement with the inside channel definingsides of the track supports 62, 64, 66, et seq., this in order to assistin maintaining their position within the supports during completion ofinstallation.

Referring now to FIG. 7, an exploded illustration similar to FIG. 2 of afurther embodiment incorporating a plurality of reconfigured and channelrail mounted twist lock fasteners, each of which including a flatrectangular shaped base 86 which is dimensioned for seating in laterallyslidable fashion within the open channel interior defined in relation toeach rail 10, 12, 48, 50 (as previously described in the precedingembodiments). The inserting base 86 in turn supports a reduceddimensioned fixed portion 88 which in turn seats through the linear slotdefined between inner extending walls 36 and 38 (this as best shown inFIGS. 8 and 9 and such that the both the fixed portion 88 and underlyingchannel seating base 86 are permitted to slide but not rotate relativeto the rails). FIG. 7A is an enlarged perspective of a modified twistlock fastener exhibiting a lengthened fixed support portion 88′extending from the base 86 and for accommodating any of thicker filterscreens, multiple layer screens, or other coverings;

A further twist and lock portion 90 is mounted via a pin or stud in arotatable fashion relative to the fixed support 88. A screen or likecovering 92 exhibits a flexible or rigid perimeter extending edge 94within which is defined an array of perimeter spaced apart rectangularapertures 96 (as opposed to circular apertures 28 depicted in thevariant of FIG. 1). Without limitation, the apertures in the coveringcan also exhibit any other shape or profile.

In this fashion, and upon the twist lock portions being first rotated toa flush profile with the underlying fixed portions 88 (FIG. 7), thefasteners are prepositioned within the rails so that the twist lockportion 90 and the upper part of the underlying fixed portion 88collectively seat through the apertures 96 (see FIG. 9). At this point,the twist lock portion 90 is rotated ninety degrees about a horizontalaxis (see arrow 98 in FIG. 8) and so that an offset portion of theunderside of each twist lock portion 88 prevents removal of the covering92.

FIG. 8A is an illustration similar to FIG. 8 of a variant of the twistlock fastener for supporting a dual layer screen, see at 92 and 92′ withcorresponding reinforced edges 94 and 94′, upon a selected elongatedsupport track. FIG. 9A is a corresponding side view of the twist lockfastener of FIG. 8A in engagement with the dual layer screen 94/94′.

In this manner, the various fasteners are capable of being prepositionalong either or both of first and second opposing pairs of surfacemounted rails 10/12 and/or 48/50 in a manner which facilitates quicklocation, installation and removal of the covering. The coveringmaterial 92 can again include any type of screen or mesh as well as alsocontemplating the use of impermeable covering or insulating materials.It is further envisioned that the outer perimeter or binding 94 of thecovering material can include either rigid or flexible materials.

Referring to FIG. 10 in combination with FIGS. 11-12, another explodedillustration similar to FIG. 7 is provided of a yet further embodimentincorporating a plurality of reconfigured and channel rail mountedtoggle lock fasteners. Each of the toggle lock fasteners includes agenerally flat and rectangular shaped channel seating base 100 of ashape and dimension similar to that previously identified at 86 inregards to the twist lock fasteners of FIG. 7 and such that the togglelock fasteners can be channel inserted for lateral displacement withinthe associated surface mounted rails 10/12 and 48/50 (see again FIG. 12)or at 62, 64, 66, et seq. (FIG. 6A).

Each of the toggle lock fasteners further includes a pair of spacedapart tabs 102 and 104 projecting from each base 100 in a manner whichpermit outermost portions thereof to project beyond the spaced apartchannel defining surfaces 36 and 38 associated with each selected rail(and as shown in cutaway in FIG. 12 in relation to selected rail 10). Acylindrical shaped toggle element 106 is mounted about a vertical axisdefined by a pin 108 extending widthwise through the toggle andsupported to the tabs 102 and 104. In this fashion, the toggle lockfasteners are first pre-positioned within the channel rails 10, 12, 48and 50, following a modified array of spaced apart apertures 96′associated with the flexible or rigid binding or perimeter 94 associatedwith the covering 92 are mounted over the toggle elements in theperpendicular extending positions shown in FIG. 10 relative to thesupport base 100, following which the toggle elements 106 are rotated tothe position of FIGS. 11 and 12.

FIG. 10A illustrates one non-limited example of a substitutablemodification of toggle lock fastener as compared to that described inFIG. 10 and in which a pseudo-cylindrical shaped post or body 110extends from a reconfigured channel seating base 100′ (this includingsuch as dovetail apertures defined therein for receiving other types ofmounting fasteners in other applications separate from sliding insertionwithin the rail channels as described herein). The generally cylindricalshaped body 110 is solid proximate its integral mounting location withthe flat and rectangular shaped channel seating base 100′ and includes apair of extending ears or lobes 112 and 114, these in turn establishingan inner slot or channel having a desired profile for seatingtherebetween a generally planar, curved edged and rotatable toggleelement 116 mounted for rotation between the ears or lobes 112 and 114via a horizontal pin 118.

The toggle fastener depicted in FIG. 10A is both installed andmanipulated in a substantially identical fashion as compared to that inFIG. 10 and it is further envisioned that other variations of eithertwist or toggle lock fasteners can be employed within the scope of theinvention. FIG. 10B is a perspective of a further variant of a togglelock fastener of FIG. 10A exhibiting a lengthened fixed support portion110′ for accommodating any of thicker filter screens, multiple layerscreens, or other coverings, and such as is again reflected by the duallayer covering arrangement of FIGS. 8A and 9A.

FIG. 13 is an exploded illustration of a yet further embodimentincorporating a plurality of reconfigured and channel rail mounted hookfasteners including base shaped channel rail supports 120 from whichproject hook shaped elements 122. The covering material 92 exhibits aseries of apertures 124 arranged in spaced apart fashion about an outerflexible or rigid perimeter of the covering, such further includingreinforced ringlets or grommets (both plastic or metal) for preventingtearing of the binding, with the further understanding that suitablerectangular shaped outer reinforcements can also be integrated into thecovering apertures 96 and 96′ depicted respectively in FIGS. 7 and 10.FIG. 14 is an enlarged, assembled and corner perspective of theembodiment of FIG. 13 and illustrating a selected corner located hooksupporting fastener 122 in an engaged position relative to an outerreceiving location (aperture) 124 of the outer covering 92.

FIG. 16 is an enlarged, assembled and corner perspectiveof the embodiment of FIG. 15 and illustrating a selected corner locatedcarabiner, see spring biased portion 126 pivotal relative to a hook mainportion 127, and shown in an engaged position relative to an outerreceiving aperture 124 of the reinforced outer covering 94 of thematerial 92.

FIG. 17 is an environmental view of a further application of fastenerand channel rail mounted assembly (this depicting for exemplary sake thetwist lock fasteners 90 previously described in FIGS. 7-9 and which areinstalled over a plurality of three edge proximate interconnectingchannel rails (not shown but generally corresponding to top rail 10 andside rails 48 and 50 with bottom rail 12 deleted) in turn secured toedge proximate extending locations associated with any type of opening(also hidden from view), and such as further depicted as an enlargedgarage door or like opening associated with a structure 128. A suitablydimensioned covering material 130 is provided and which can againinclude any type of breathable mesh or impervious material, about whichextends either a flexible or rigid binding or perimeter through whichare formed a suitable array of spaced apertures (such as previouslydepicted at 96 in FIG. 7) for facilitating installation of the material130.

Finally, FIG. 18 is a yet further environmental view of a yet furtherapplication of fasteners (again twist lock type fastener 90) appliedover a window type opening about which are secured an arrangement offour rails 10, 12, 48 and 50 in the manner previously described. Acovering 132 is depicted mounted over the window or like opening (notshown) associated with a structure 134, and which may again possess asimilar arrangement of binding edge extending mounting apertures forreceiving the individual twist lock portions 90. The covering 132 isfurther depicted as a plasticized or other impervious material (suchfurther optionally exhibiting transparent or translucent properties) asa winterizing cover and as opposed to alternate use with a seasonal andbreathable mesh depicted previously at 92. In this fashion a variety ofdifferent covering materials, varying by weight and or construction, canbe provided as alternate covering for different seasons (e.g. meshmaterial in summer and impervious/heavy duty sealing cover for winter).

Referring to FIG. 19, a partially exploded perspective is shown of afurther valiant of the assembly and illustrating the plurality ofmodified elongated track defining supports previously depicted at 62,64, 66 (and further at 67), secured to the air intake face of theassociated structure 4 surrounding the central opening. As previouslydescribed, the track defined supports can exhibit any desired crosssectional shape or profile and may, in one non-limited example, beconstructed of an aluminum, plastic or other suitable extruded, stampedor otherwise formed material.

As further shown, the track supports may exhibit a modified “U” shapedinner channel or profile for receiving the inserting portions of thevarious fastener arrangements for securing the filter or mesh to thearranged track supports. As will also be described and shown inadditional detail, the supports have an increased cross sectionalthickness, with their cross sectional interior channels exhibitingirregular or stepped surfaces (as compared to the channel supports 10,12 in FIG. 1).

FIG. 20 is a cross sectional cutaway of a selected track support 62 fromFIG. 19 and illustrating an underside positioned magnet 132 (see alsoFIG. 33) for assisting in releasably securing the support in extendingfashion along a metal receiving surface of the intake face 4.Corresponding FIG. 32 is a cutaway plan illustration of selected tracksupport 62 and depicting a two-sided adhesive tape 134 backing forsecuring the support to an intake face location.

FIG. 34 is a further plan illustration similar to FIGS. 32-33 of a glue136 for attaching the track support 62 to the intake face location. FIG.35 is a yet further plan illustration of a conventional screw, again at20, passing through an aperture 138 in a base of the track support formounting to the intake face location.

Proceeding to FIG. 21, an illustration is provided generally at 140 of aselected twist lock fastener utilized in the engagement protocol of FIG.20. Similar to the twist lock variant previously disclosed, a generallyplanar base 142 is adapted to being received within the open end of theinterior channel or track defined in the elongated support, a fixed bodyportion 144 extending from the base and concluding in an end supporttwist lock portion 146 (see further rotated position 146′ depicted inphantom). The base 142 further exhibits widened end support locations148 and 150, these being dimensioned for facilitating frictional andpositional fitting within the interior track defining sides, see at 152and 154 of the support 62 in FIG. 20, concurrent with the upper edgesurfaces of the base 142 abutting the forward inside edges 156 and 158associated with the narrowed slot, a rear or back surface 160interconnecting the sides 152 and 154 and completing the interiorchannel profile.

FIG. 22 is a cross sectional cutaway of a selected track support 62 aspreviously shown in FIG. 20 and illustrating a variant 140′ of the twistlock fastener exhibiting a lengthened fixed support portion 144′. FIG.23 is an illustration of the modified twist lock fastener, similar tothat shown in FIG. 21, and exhibiting the fastener 140′ installed in thetrack support 62 such that the lengthened fixed support portion 144′ iscapable of accommodating any of thicker filter screens, multiple layerscreens or materials (see as depicted at 92/92′ with dual layers ofreinforced edges 94/94′ and aligning ringlet or grommet definedreceiving apertures 92. As with the variant of fastener in FIG. 21, thewidened base locations 148 and 150 facilitate frictional engagementalong the interior side edges 152 and 154 of the supports.

FIG. 24 is a partially exploded view of a support track arrangementaccording to a modification of FIG. 19 and which includes the provisionof intermediate end-to-end 162 and 164 and corner/angled 166, 168, 170,et seq. adaptors or plugs for assembling running lengths of supporttrack (see further at 62/62′, 66, 68, et seq.) in varying arrangementsupon the air intake face. The intermediate adaptors 162 and 164, asshown, each exhibit a central support from which project a pair ofopposite engaging portions 172/174 which are adapted to engage theinterior defined channel ends of the supports. The corner/angledadaptors each further include a generally “L” shape with engagingportions 176 and 178 for joining angled ends of the support track, suchas in the perpendicular arrangement shown.

FIG. 24A is a similar illustration to FIG. 24 and showing a variant ofthe corner adaptors/plugs, at 180, 182, 184, and 186 for providing theassembled support track as a rigid standalone frame with a seamless edgeappearance. As further best shown in kit assembly view of FIG. 39, themodified corner plugs 180-186 each include an additional outer “L”shaped embossed portion, see at 188, 190, 192 and 194 corresponding toeach plug 180-186. Upon the angled projecting portions (see further at196 and 198 for selected plug 180) seating within the interior channelsof associated angled supports 62/66, the outer embossed portions (188)of each corner plug seats against the ends surfaces of the channels toestablish the seamless appearance shown.

FIGS. 24B-24C respectively illustrated exploded and assembled views of afurther three sided variant of linear end-to-end adaptor, see at 191,which is configured to attached abutting opposing ends of first 62 andsecond 62 selected running lengths of support track, these being shownin reduced length. As best shown in FIG. 24B, the three sided linearadapter 191 exhibits a generally reverse “C” shape in cross section anddefines an inside configured profile (see interconnected surfaces 193,195 and 197) which is adapted to slidingly receive and seat the opposingends of the track 62/62′ in abutting fashion.

The adapter 191 can include any flexible material, such as a heavy dutynylon or plastic which has a high degree of resilience and, as furthershown, is flexibly applied over the three projecting sides of theopposing mating ends of the track sections 62/62′, so that the end-mostopposing track sections are thereafter frictionally gripped andrestrained within the inner “C” defined surfaces 193, 195 and 197.Without limitation, the opposing ends of the tracks can be insertedwithin the adaptor 191 (as well as the adaptor variant depicted at162/164 in FIG. 24), either prior or subsequent to mounting the tracksections to the air intake face. In this fashion, the present inventionsprovide for a rigid stand-alone frame construction for supporting thescreen or other covering.

As further understood, the construction of the connectors/plugs caninclude a compressible polymer or the like (such also potentiallyincluding a foam outer layering) which can frictionally seat within theirregular end profile of the supports and facilitates seating engagementbetween the linear end-to-end or angled supports and thereby providesfor secure and seamless engagement between the interconnected sectionsof track support.

FIG. 25 is a partial corner depiction, generally at 200 of a furtherjoining arrangement established between perpendicular arranged supporttrack 202 and 204, such having a mitered appearance and within opposingends of which the angled corner adaptor 166 is frictionally seated. FIG.26 is a corresponding corner depiction, generally at 206, showing themodified corner adaptors of FIG. 24A. FIG. 27 is a further variant of athree dimensional triangular enclosure 208 utilized with any variant ofcorner plug/adaptor and for providing additional structural supportbetween angled extending ends of support track 62 and 66;

FIG. 28 is an illustration of a further variant of screen attachedgrommet in the form of a two-piece sandwich configuration 210 and 212for inter-engaging through opposite sides of a reinforced cornerlocation 214 of an associated screen 216. The grommets each include aplanar disc shape with the first piece 210 having perimeter definedapertures 218 and a central receiving aperture 220. The second piece 212likewise includes a plurality of prongs 222 projecting from a surfacethereof (a central aperture 221 also defined in the piece 212) andwhich, upon piercing through the covering or screen 216 (see as depictedby aperture patterns 224, 226, et seq. defined in the reinforced edge214) resistively engage and seat within the perimeter defined apertures218 of the first piece 210 in order to mount both pieces together onopposite sides of the material with the inner apertures 220/221 inalignment.

The two piece grommet assembly can also be utilized with a knife edgesuch that, and upon mounting in sandwiching fashion about the screen(not previously apertured such as at 224/226), the knife edge can beutilized to cut out the screen portion revealed by the mating aperturedefining inner perimeter surfaces 220/221, this in order to create thenecessary interior aperture for receiving the selected fastener portion.FIG. 29 is a further partially exploded plan view of the assembledscreen grommet of FIG. 28 in combination with the twist lock fastener(140) of FIGS. 21 and 23.

FIG. 30 is an illustration similar to FIG. 28 and depicting anunreinforced screen 228 utilized in combination with the two pieceassembleable grommet 210/212. As with the embodiment of FIGS. 28-29, thetwo pieces are assembleable in a manner which sandwiches a perimeterlocation of the screen 228, such as which can exhibit pre-aperturedlocations 230, 232, et seq.

Alternately, the screen 228 can be provided in stock form without anypre-incisions, such as along the perimeter receiving locations forreceiving the grommets. The screen 228 can be sized, on site, such aswith the use of a knife edge. It is also envisioned that the variationsof the prongs 222 can also include rounded end locations (see at 234 incutaway in each of FIGS. 29 and 31) which are sufficiently deformable inorder to pass through the interior profiles defined by the matingapertures 218 of the grommet piece 210, and subsequently engage thereverse (rear) surface locations of the piece 210 in order to maintainthe sandwiched locations of the grommets pieces 210/212 with the screentherebetween. FIG. 31 is a further partially exploded plan view of theassembled screen grommet of FIG. 30 in combination with the twist lockfastener of FIGS. 21 and 23.

Proceeding to FIG. 36, a front plan illustration is generally shown at234 of a square track support arrangement (see supports 62, 64, 66 and67) in combination with the triangular three dimensional corner supports208 of FIG. 27. The corner supports, as previously described, eachinclude a triangular 3D construction and exhibit a hallow interior andcan be concurrently fastened to the air intake surface for providingaligning and retaining support between opposing arrayed ends of tracksupport, such further attached fixedly or removably in any fashiondesired and which can further include any of end-to-end, mitred or otherinterconnecting arrangement.

FIG. 37 is a front plan view, similar to FIG. 36, of a rectangularsupport track arrangement 236, such as which can be assembled using thelinear adapters 162/164, in combination with pairs 64/64′ and 66/66′ ofelongated track supports in combination with upper 62 and lower 67interconnecting supports. FIG. 38 is a further front plan view of atriangular support track arrangement 238 and which is shown with threesupports 65, 66 and 67 along with a modification 208′ of the threedimensional corner supports. The triangular arrangement 238 is providedto support the proposition that the supports can be configured orarrayed in any perimeter extending fashion for covering any type of airintake opening.

FIG. 39 is a kit illustration depicting one non-limiting combination ofitems utilized in the method and assembly of constructing a screen, meshor other covering supported upon the intake face over the air intakeopening. As described, the kit and assembly can include a selectedplurality of the support tracks, 62, 64, 66, 67, et seq., stock filteror other flexible mesh or non-mesh material 228, assembleable grommets210/212, any type of fastener (represented by twist lock fasteners 140of FIG. 21), and any combination of linear end-to-end 162/164 andangled/corner 180, 182, 184, et seq. interconnecting adaptors accordingto any one of a number of non-limiting variant of the presentinventions.

As further shown, the supports 62, 64, 66 and 67 can include magneticbackings 132 (or alternatively any other permanent or removable mountingoptions as previously described not limited to adhesives, adhesive tape,fasteners, glue, etc.). Advantages of the present invention include theability to both quickly install any desired covering material utilizingany of the fasteners previously disclosed, combined with theself-aligning aspects provided by the combination of channel rails andfasteners, this in order to accommodate variations in productiontolerances of the filter as it translates to installation and alignmentwhen installed.

Referring now to FIG. 40, a perspective is generally shown at 240 of aselected corner insert similar to that depicted in FIG. 39 according toa further embodiment. In combination with the “T” shaped intermediateinserts, further depicted at 242 in FIG. 42, the inserts according toone non-limiting variant can be configured with recess pockets, thesedepicted by recess pocket 244 configured within reverse perspective ofinsert 240 as in FIG. 41, and further pocket 246 depicted within insert242 depicted within reverse perspective of FIG. 43.

As representatively shown in FIG. 41, each of the pockets (againreferencing pocket 244) exhibits four perimeter defining walls, see at241, 243, 245 and 247 which, in combination with a recessed base wall249, establish the recessed interior of the overall pocket 244.Referencing again the selected corner insert 240 in each of FIGS. 40-41,in comparison to the corner plugs or inserts 180-186 previouslyillustrated at 180-186 in FIG. 39), such again includes first 250 andsecond 252 angled interconnecting sides, in combination with anadditional outer “L” shaped embossed portion, such as shown at 254 withfront 255 and rear 257 raised profiles, and as compared to thatpreviously depicted at 188, 190, 192 and 194 corresponding to each plug180-186. Upon the angled projecting sides 250/252 (compared to similarangled sides or portions at 196 and 198 for selected plug 180 in FIG.39) seating within the interior channels of associated angled supports62/66, the outer embossed portion (254) of each corner insert abutsagainst the ends surfaces of the interconnecting lengths of channels toestablish the seamless appearance previously shown in FIG. 24A for theoverall track assembly.

Without limitation, the inserts 240 and 242 can each be constructed of asuitable semi-rigid to substantially rigid plastic, nylon or othermaterial and such that, upon assembly, the insert can provide anydesired degree of dynamic resistive fitting or controlled crush orcollapse when engaged with the receiving open ends of theinterconnecting track sections. This can be enhanced by dimensioning thetrack interior receiving insert portions 250 and 252, order to provide adesired degree of collapsibility associated with the hollow interiorpockets 260 and 262, respectively. Alternatively, and as will be furtherdescribed, the inserts or connectors can be constructed of any othersuitable material, not limited to a flexible plastic, and including anyconstruction incorporating any type of crush line or collapsiblelocations define in or upon the insert portions.

As further depicted in the reverse perspective views of each of FIGS. 41and 43, and in addition to the central receiving pockets 244 and 246,the extending or angled sides of the inserts 240 and 242 (as again shownat 250/252 for corner insert 240 and as further shown at 256/258/260 forT connector insert 242) each includes a similar recess pocketconfiguration with interconnecting and inner perimeter defining wallsurfaces such as associated with the central interior receiving pockets244/246. For purposes of ease of illustration, reference is made to therelevant drawings and without each wall surface being necessarily calledout and referenced by number. This is further shown again at 260 and 262for the insert extending pockets in FIG. 41 (corresponding to angledsides 250/252, and further at 264/266/268 in FIG. 43 (corresponding to Tshape defining sides 256/258/260).

Without elaboration, and as is concurrently described in FIG. 41 withreference to the corner connectors) each of the interiorly configuredpockets is typically exposed to the rear surface of the selected insertand are each defined by a recessed base surface and interconnectedinterior side surfaces.

A further variant of insert 240′ is depicted in FIG. 41A whichillustrates a smooth exterior facing surface 255′ (contrasting tocentral embossment surface 257 in FIG. 40), against which can be secureda combination adhesive portion and peel away layer 261, this revealing atacky surface 263 in order to press-fit the insert against the intakesurface 4. As further shown, the insert portions can be reconfigured, at250′ and 252′ to exhibit solid rather than recessed constructions, suchpotentially including the insert portions incorporating any crush orcontrolled collapsible materials to enhance gripping within the trackreceiving interiors.

FIG. 41B is a further example of a corner or “L” insert 240″, similar inconstruction to that shown in FIG. 41A, and illustrating a cylindricalrecess 265 with an enlarged recessed and undercut location (further inphantom at 267). A screw fastener 269 can be provided for anchoring theinsert 240″ against the intake face 4 of the air handling unit (or othersupporting structure), typically after the inserts have beenfrictionally fitted into the opposing receiving ends of the tracks inorder to define a cover supporting perimeter.

In accordance with the present description, and further to thatpreviously described, the inserts or connector portions can include anytype of plastic, rigid foam or other material which can flex or collapsein a controlled fashion in response to being inserted within the intakechannel and in order to provide the necessary gripping aspect incombination with the retaining forces exerted by the magnet. To thisend, the various inserts can be provided in plural form with theassembly kit aspect of the present invention and which, following aninitial assembly of the system, can be subsequently disposed offollowing a successive disassembly and removal from the air intake face,with additional replacement inserts provided in substitution inassociation with a future re-assembly of the system.

Concurrent with the controlled collapse or crush-line performance of theinserting portions (recessed as shown at 250/252 in FIG. 40 or solid asshown at 250′/252′ in FIG. 41A) of the corner “L” and of the “T” shapedinserts, the recessed interior pockets 260/262 (“L” shaped corner insertof FIG. 41) and 264/266/268 (“T” shaped insert of FIG. 43) may alsoprovide a degree of dynamic compression to the extending sides of thecorner “L” and intermediate “T” connectors, thereby providing additionalcompression fitting forces exerted against the inside end-to-endsurfaces of the channels 62, 64, 66, et seq. As further shown, theinsert 240 includes an additional inner angled embossment (seerectangular shaped portion 270 on a forward inner angled and which isalso provided on an opposite and hidden rearward facing location) andwhich, in combination with the outer “L” shaped embossment 254, providesthe desired abutting and seamless appearance in combination with theplanar extending end surfaces of the channel defined tracks 62, 64, 66et seq.

Similarly, the “T” shaped connector 242 (see FIG. 42) includes an upperlinear embossment 272 and lower inner edge embossments 274/276 which, incombination, provide seamless engagement between three extending tracksin the manner depicted in FIG. 44. Both of the “L” corner andintermediate “T” connector include embossments on both opposite faceand, as shown in the illustration of FIG. 24A, in order to provide aseamless edge appearance.

The ability to support intermediate extending lengths of track, shown at68′ in FIG. 44, provides additional lateral support to the filterextending across the middle of the intake opening, such as in responseto the flow of air. The cross section of extending sides 250/252 (insert240) and 256/258/260 (insert 242) is further such that they seat withinthe cross sectionally defined interior (see surfaces 154-160 aspreviously described in track 64 in FIG. 19).

FIG. 44 is an exploded view of a perimeter defining assembly includingreduced length sections of channel defining track, again 62, 64, 66, etseq., along with corner 240 and intermediate “T” shaped 242 inserts, forapplication to an air intake face in combination with any type overpermeable or impermeable covering (not shown) which is secured inadhering and overlaying fashion across the perimeter defining tracksurface via any type of fastener not limited to that previouslydescribed. Without limitation, and as previously described, the rearmounting surfaces of the underlying tracks can be secured to the intakeface covering by any of magnets, adhesives or mechanical fastenersincluding mounting screws. FIG. 45 further depicts an assembledperspective of a non-limiting example of an assembly according to theinvention.

FIG. 46 is an assembled and corner cutaway view taken along line 46-46of FIG. 45, through an interior track 62 location, with FIG. 46A takenthrough a selected inserting portion of a selected corner insert andwhich shows the biasing or compressed nature of the insert portion (e.g.at 250 in FIG. 40) within the inner receiving surfaces of the track 62.A plurality of dimples or protuberances (see at 281 and 283 in FIG. 46A)can be configured upon the outer opposite engaging surfaces of theselected and indicated insert portion 250, such collapsing and/orbiasing against the inside surfaces of the receiving track 62 forfrictionally retaining the inserts in places. As further described, theprotuberances 281/283 can further include crush portions which wouldprompt replacement of the inserts upon removal and subsequentreinstallation of the overall track assembly (FIG. 45).

Consistent with the above descriptions of FIGS. 45-46A, it is furtherthe understanding that it is the compression extending sides of theinserts 250/252 or 256/258/260 (see cutaway of “L” insert side 250 inFIG. 46A) which actually seats within the exposed ends of the tracks(again at 62 in FIG. 46A), with the magnet supported within the insertproximate the end-to-end or angled track locations as again shown inFIG. 45. Accordingly, and for purposes of ease of illustration, thedepictions of FIGS. 45-46 are interpreted to include, in one variant,the provision either of an insert 240/242 (hidden from view) and withinwhich the magnet 248 is adhesively mounted (see layer 278) in the mannerdepicted in FIGS. 41/43, collectively or independently from theprovision of the crush ridges 251 or dimples 253. As previouslydescribed, twist lock fasteners 144/146 are provided for securing eithera single or multi-layer screen configuration (see as previously shown inFIG. 20 or repeated in FIG. 22 with dual screens 92/92′ and reinforcedouter edges 94/94′).

FIG. 47 is an exploded view similar to FIG. 44 and further illustratinga central interior and “X” or cross shaped insert 278 and additionalchannel tracks, see further for example at 64′ and 68′, additional tothose shown in FIG. 44 for providing a reinforced interior supportextending over the intake opening according to a further variant. Thecross shaped insert 278 is comparable in construction to a selected “T”shaped insert 242, with the exception of a further and fourth extendingside for positioning/integrating the insert 278 at a central location ofthe assembled frame in order to provide interior support to the outerfour interconnecting sides, corresponding to a plurality of four outerand intermediately positioned T″ shaped inserts, the “X” shaped insert242 corresponding to a central interior location of the supported screenor covering relative to the intake opening.

FIG. 48 is an illustration of a further corner insert 280 according toan updated variant and which provides frictional engaging ramps orembossments, further located at 282 in relation to opposite engagingsurfaces of inserting portion 284 as well as at 286 in relation toopposing engaging surfaces of inserting portion 288, and in order tofrictionally grip the interior of each track. The ramps/embossments canexhibit any configuration and, as shown, depict elongated raised stripswhich extend along the outer end faces of the insert portions 284/288 inorder to establish crush ridges when compressed within the trackreceiving interior.

The “L” insert 280 depicted in FIG. 49 is otherwise substantiallyidentically constructed to that shown in FIG. 40 and can include acentral embossment (see further opposite outer “L” shaped locations)along with opposite central inner embossed locations, see central outerembossments at 290 and central inner embossments 292 for the visibleside and which, when received within the selected track interiors,defines the overall desired seamless appearance.

FIG. 48A is a similar illustration of FIG. 47 of a related “L” insertand in which the linear strip shaped ramps 282/286 are alternativelydepicted as tapered ramped portions 282′ and 286′ disposed upon opposingsurfaces of each track engaging insert portion. The degree and directionof the taper can be modified, such as in order to provide differentfrictional or compression engaging properties in contact with theinterior surfaces of the track receiving portion.

Proceeding to FIG. 49, shown is an exploded view of a further variant offrictional engagement of an insert 294 utilizing triangular and widthextending embossed profiles, see pairs at 296 and 298, such as which areshown extending crosswise in association with opposite engaging faces ofthe end extending insert portions of the associated fastener. Alsooptionally depicted on an interior of a reconfigured track portion 62′are opposing receiving profiles, see at 300, the location of which isintended to receive/seat the embossed profiles 296/298 in a manner toenhance the frictional engagement of the insert embossments. Thereceiving profiles 300 are understood to be optional and can includeoffset ridged or recessed sections (the opposing embossed profilesfurther understood to include crush portions which operate effectivelyin opposition to flat surfaces associated with the track interior).
